SEAT POST:
Campagnolo Record - pre 1978 non-fluted one piece cast aluminum alloy construction without any "limit line" - pre 1978 two bolt dual pivot clamp with solid pivot boss - 23 mm offset - 180 mm x 26.4 mm - model 1044 ... [Correct as original, inasmuch as I did see fit to replace both the upper and lower mounting brackets as well as the corresponding barrel nuts and adjusting bolts with NOS versions of same. The remainder of the seat post hardware would be absolutely original to this bike.]
